Perguntas frequentes
Can someone open an encrypted PDF without the password?
No. Standard AES-128 and AES-256 encryption are mathematically secure against brute-force attacks when paired with a strong password.
Does iEditPDF store my passwords or encryption keys?
Never. Encryption is executed entirely inside your browser's local JavaScript/WebAssembly memory space. We have no servers storing documents or credentials.
